AXING BVS 20-66 - Handbuch (Seite 4)

Testports Input Output
RF Installation:
4 Connect the input of the amplifier to the
interconnection point. Connect the output of the
amplifier to the antenna sockets or the taps
used.
4 Use a highly shielded coaxial cable with an F
connector. Suitable cables and connectors can be
found in the current AXING catalogue or under
www.axing.com.
4 The test ports at the input is bi-directional. This
test point has to be activated or deactivated with
the adjacent jumper.
Grounding and Mounting:
To avoid dangerous power surges (e.g. risk of fire and electrocution), all
devices have to be grounded according to EN 60728-11. Use the screw
terminal at the device (3).
Use the mounting screws included in the delivery and the mounting holes of
the devices (4).

Remote power feeding of BVS
20-66:
The BVS 20-66 is supplied over the
coaxial cable. The jumper (JS) is used
to decide between remote power
supply at the input (position
"Eingang") or at the output (position
"Ausgang"). Install according to this a
power inserter TZU 15-01 at the input
or at the output of the amplifier.

Field of application:
The devices are suited only for amplifying radio and television signals in the
house! If the device is used for other purposes, no warranty is given!
The illustrations show application examples for the distribution in star (1) and
tree structure (2).
Adjustments of gain and slope:
Gain and slope are adjusted (continuously variable) with the control buttons
(DS 1 and DS 2) in the forward frequency range.
With control button (US) one adjusts the gain (also continuously variable) of
the return path before the amplifier stage.
The jumpers (DS J1 and DS J2) are used to adjust the interstage attenuation
and slope in the forward frequency range.
The jumpers (US J1 and US J2) are used to adjust the interstage slope and
attenuation of the return path.
Power indicator LED:
The amplifier comes with LED (POWER) which shows the operation mode:
! green = in operation
! out = no power supply
